Customizable Twin Shaft Sizer For Coal, Gypsum, Iron Ore,Nickel Ore

As an efficient crushing equipment, Twin Shaft Sizer has been widely applied in the primary, secondary and tertiary crushing stages of mineral processing. It demonstrates excellent adaptability, whether in small-scale operation lines with lower processing capacity or in large-scale continuous production systems in mines, and can be seamlessly integrated with equipment of low, medium and high tonnage. Moreover, Twin Shaft Sizer is not only suitable for continuous operation in open-pit mines but also well meets the crushing requirements in underground mines with limited space, thus having a wide range of application scenarios.

 

In terms of technical features, the Twin Shaft Sizer adopts a low-speed and high-torque drive system, which ensures efficient crushing while significantly reducing vibration and noise during operation and extending the service life of the equipment. Additionally, the device integrates a unique tooth profile design independently developed by our company, which enables more uniform force application on the materials during the crushing process. This effectively improves the uniformity of the output particle size and reduces the proportion of fine powder materials. This characteristic has a positive impact on subsequent screening, conveying, and further processing stages, contributing to the stability and economic efficiency of the overall process flow.

 

 

 

Twin Shaft Sizer crusher utilizes the shear force and tensile force between the toothed rollers to break the materials.

 

Twin Shaft Sizer has two inwardly rotating toothed rollers with replaceable crushing teeth. The most suitable feeding method is by apron feeder or screening equipment, which conveys the material at a uniform rate and distributes it evenly over the toothed rollers.

1.The mineral is gripped by the leading faces of opposed rotor teeth,and to be subjected to stress under the concentrated load of the rotor teeth.The stress causes mineral to be break along its natural texture.

2.Mineral is broken in tension by being subjected to a three point loading, which between the front tooth faces on one rotor and rear tooth faces on the other rotor.

3.For the mineral that has not been fully broken, through the rotor teeth and fixed teeth of the breaker bar can be further broken to ensure the 3d dimension requirements of the discharging material.

 

 

 

 

 

 

Toothed roller can be divided into Primary Twin Shaft Sizer Toothed Roller and Secondary Twin Shaft Sizer Toothed Roller. Easy installation and disassembly of the Twin Shaft Sizer tooth head, which can significantly reduce the maintenance time and lower the maintenance cost.

 

The feeding granularity of primary sizers is less than or equal to 1500mm and the discharging granularity is less than 300mm. The arrangement of crushing tooth shapes and tooth shapes are arranged by special spiral tooth shapes. The crushing teeth are cast from abrasion resistant and impact resistant alloy steel. Primary Sizer toothed roller has a unique and novel tooth design structure with deep spiral distribution for high productivity. The passing cavities are formed between the two toothed rollers and the side plate body for screening and crushing materials respectively.

 

The Feeding size of Secondary sizer less than or equal to 300 mm (a small amount of 400mm is allowed), and the discharging granularity is less than 50mm. The connection form of the teeth plate adopts a single dovetail groove, which is complementary to the bevel of the insert clamping block, and then the crushing tooth plate is installed on the fixing seat of the teeth plate, formed a surface to surface connection, which is tightened and pressed by high-strength bolts. The function of the bolt becomes a fixed insert clamping block, avoiding the problem of the fixed lock bolt breaking, teeth plate falling off or difficult to disassemble and replace.
